Wireless Installation Considerations

The D-Link wireless internet camera lets you access your network using a wireless connection from virtually anywhere
within the operating range of your wireless network. Keep in mind, however, that the number, thickness and location
of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to
maximizing wireless range is to follow these basic guidelines:

1. Keep the number of walls and ceilings between the D-Link adapter and other network devices to a

minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.

2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a

45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.

3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on

range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that

generate RF noise.

5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and

home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.

the bit rate, but cause image to be corrupted longer if there is packet loss while transmitting. The video quality
may be poor due to the sending of maximum frame rate within the limited bandwidth when images are moving
rapidly. Consequently, to ensure detailed video quality (quantization rate) regardless of the network, it will utilize
more bandwidth to send the maximal frames when images change drastically.To fix the bandwidth utilization

This setting is easier to use when image quality does not have to be precise. Below is a typical file size after 1

White Balance is related to the color temperature. Color temperature is a way of measuring the quality of a
light source. It is based on the ratio of the amount of blue light to the amount of red light, and the green light is
ignored. The unit for measuring this ratio is in degree Kelvin (K). A light with higher color temperature (i.e., larger
Kelvin value) has “more” blue lights than a light with lower color temperature. The default setting for the camera
is “Auto”.

Section 3 - Configuration

Recommendations for Setting Video for the Best Performance:

“Best performance” means the image refresh rate should be the fastest possible and the video quality should be the
best possible at the lowest network bandwidth possible. Three factors, Maximum frame rate, Fix bit rate, and Fix quality
in the Video Configuration page, are related to performance.

Recording settings for real-time motion images

To achieve a real-time visual effect, the network bandwidth should be large enough to transmit 20 image frames
per second (fps) or more. If you are on a broadband network over 1 Mbps, you can set Fix bit Rate to 1000Kbps or
1200Kbps, or set Fix quality to achieve the maximum frames. The maximum frame rate is 25 in 50Hz system and 30 in
60Hz system. If your network bandwidth is more than 384Kbps, you can adjust Fix bit rate according to your bandwidth
and set the maximum frame rate of 25 to 30.

If the images vary dramatically in your environment, you may slow down the maximum frame rate to 20 to decrease the
transmitted data for better video quality. Since the human eye could not easily differentiate between 20 and 25 or 30
frames per second, the slower frame rate will not be noticed. If your network bandwidth is below 384 Kbps, you should
adjust the bit rate according to your bandwidth and experiment to allow for the best frame rate that can be achieved.
The faster frame rate in a slow network will blur the images. You may also try to choose 320x240 in size option for better
images or 640x480 for larger image size. Because the network has burst constraints and everyone’s environment is
not the same, any poor connection will impair normal performance.

Recording settings for clear identification for each image

To have the best video quality, you should set Fix quality to detailed or excellent and tune the Maximum frame rate to
suit your network bandwidth. If you get some broken pictures in a slow network, you can set TCP protocol in Connection
type for a more accurate transmission but the received images may have a lag. Note that any slow connection with
multiple users will impair performance.

Recording settings to compromise between real-time and clear images

If you have a broadband network, set Fix quality to Good image quality, or higher, instead of setting the Bit rate.
Otherwise, fix the bit rate according to your actual network speed and set the frame rate to 30. If the image quality is
low, select a lower frame rate above 15. If the image quality is still not improved, select a lower bit rate.

Indicate the size of the hard disk that will be reserved for other Windows® applications (at least 300MB).
The remainder of the hard disk space will be available for recording. The more space you have reserved,
the less there will be available for your camera(s) to record to. As you move the bar to the right, more
space will be available for your camera(s) and conversely, less space will be available for your other
applications. If the recording data exceeds this limitation, the new video data will replace the oldest data
(on a First In First Out (FIFO) basis) when “Cycle Recording” has been checked.

Video Channel Selection Area:

Primary Schedule:

Secondary Schedule:

Operation Buttons:

The video channel selection area provides the IP addresses and location information of the connected
video channels for the user’s reference. You can select a video channel in this area and create a schedule
for it.

The Primary schedule consists of the day time-line, week time-line, begin time selector, end time selector,
and event mode settings.

The Secondary schedule consists of event mode settings.

The operation buttons allow the user to manipulate the edited schedule of the selected video channel.
The scheduler can be closed from here.

The Functionalities of Configuration Components

The four main parts of the scheduler have been briefly described above. The four parts will be described in detail in
the following section.

Video Channel Selection Area

In this area you will select the video channel that you want to set a schedule for. Each video channel will display a name,
an IP address, and the location. Please note that when you switch between video channels in this area, the changes
in the schedule of the previous video channel will be saved automatically.

Primary Schedule

Schedule with Time Lines

There are two different time-lines: hour unit time-line and week unit time-line. You can make your own schedule by
plotting markers in all time-lines. These two time lines are associated with each other. That is, if you make changes in
one time-line, the corresponding changes will be applied with scale to the other three time-lines in the same schedule.
Before you begin, make sure that you select “Once” (page 83) if you want to choose the days to record on.

Week Time-Line

In the figure below, Week time-line is displayed. It includes the time-line, schedule information, and the selected day
in the week.

Marking/Unmarking the Recording Time on the Week Time-Line

The corresponding changes for the markers on the week time-line will be automatically added to the hour time-lines,
which is shown above. You can also mark and unmark the plotted bar by clicking and dragging with the left and the
right mouse button.

Hour Time-Line

In the figure below, the Hour time-line is displayed.

Section 3 - Configuration

Marking/Unmarking the Recording Time on the Hour Time-Line

You can apply the one-click function by clicking the left mouse button and dragging to mark the time on this time-line.
The operating method for the hour time-line is the same as that of the week time-lines. Please refer to the previous
section about marking/unmarking on the week time-line for more details.

Schedule with Time Picker

Begin and End Time

There are three controlling units in both “Begin Time” and “End Time” selectors shown below. The first unit of these two
selectors is the date picker. You can select day with it to set the beginning time and the ending time for the recording
interval.

The second and third units are the hour picker and the minute picker. You can change the hour and minute settings for
the beginning and ending time with them.

Note: The time set in “Begin time” must be earlier than that in “End time”. Otherwise the settings will not be applied.

Apply and Erase Buttons

After you have selected the time period with “Begin time” and “End time” picker, you can apply the period picker, shown
in the figure below, to set the periodical types of the time interval set previously. After the settings in “Begin Time”, “End
Time” and “Period Picker” are all done, you should click the “Apply” button or “Erase” button on the right to add or clear
this scheduling information to the editing schedule scheme. Note that only after you click on the “Apply” button, the
scheduling information settings will be written back into the whole editing schedule scheme. That means this edited
scheduling time interval is valid only after you “Apply” the changes.

Using the Monitor Program

This section depicts, in detail, how to manipulate the monitor tool.

Connection of the DCS-2120

Once you have the privilege to connect to the DCS-2120, the cameras will automatically appear in the video area in
the order they are connected. Once you have set up the camera in the video channel, the color of the channel number
will turn green, indicating that the camera has been added to IP surveillance. If you do not set up the camera for the
video channel, the color of the channel number will be gray.

There is a unique light signal associated with each channel number. It indicates the status of the dedicated video
channel, which is depicted as follows:

Off:

The video channel is not connected with any DCS-2120 yet.

Green:

Blink:

The green light means the DCS-2120 associated with this channel number is connected, and the video is monitored
in the video area.

Red:

The red light indicates the video from this channel is recording into the video database. In this mode, you don’t have
to drag and drop the channel to the video area. This means that this application software supports real-time recording
with and without real-time monitoring for the dedicated video channel.

With the motion detection mechanism set in the DCS-2120, the light of the corresponding channel
will blink once the motion event is triggered.

If you do not want to monitor one video, you can drag and drop the video (in the video area) to the
trashcan in the common control area of the monitor program. The following section will demonstrate
the procedures for “drag and drop” step-by-step.

Show the video of a specified channel

This section depicts the method of how to show the video of a specific channel in a display window.

Step 1: Move the mouse cursor to the camera you would like display in the window.

Step 2: Press and hold the left mouse button, and then drag it
to a display window in the video area on the right side of the
screen. Note that the cursor will change according to the area
in order to indicate whether the area is droppable or not.

Step 3: Release the left mouse button while on top of a display
window. The video will appear in the display window as shown
below. In each display layout, only one window can be assigned
to a camera. Also, each camera must have its own separate
window when displayed. Once the video is in a display window,
it can be dragged and dropped to other windows. If you drag
one camera’s video to a window that already has its own
camera’s video, the two cameras will trade display windows.
Dragging and dropping is a very convenient way to manipulate
the video channels in the IP surveillance Software.

Clicking on the “DI/DO” button shown below, you can switch to the DI/DO controls. The color of the channel number
indicates the status of the camera’s DI (Digital Input). You can click the “Switch button” to change the HI/LOW state
of the DO (Digital Output). With these features, you can monitor the remote sensor input from DI and also trigger the
camera by DO switch.

When the color of a DI/DO channel number is gray, that means the video channel has not yet
been connected to a camera.

Alert Message

If you have checked the box “Enable Motion Detect” or “Enable Digital Input” on the Camera
Configurations > Alert Settings screen, the alert message will show in the window shown

above. Once the alert, caused by motion detection or a digital input level change is triggered,
the alert message will be shown in this window. If there are more events than this window
can display, a scroll bar will appear.

The message format is described as follows:

“time”=>”alert type” #”channel number”(“win1”,”win2”,”win3”)

For example, the message “PM 02:41:00=>MO #1(0,1,1)” means that this is a motion
detection alert occurring at 02:41:00 PM in Motion Window 2 and Motion Window 3, for camera #1. If the message “PM
02:41:56=>DI #1” is listed, that means there is an alert triggered by the DI, for camera #1, at 02:41:56 PM .
